-INIPROVEMENT IN MANUFACTURE'OF KNIVES AND FORKS.

VSpecification forming part of Letters Patent No. 58,242, datedSeptember 25, 1866.

To all whom it may] concern Beit known that l, JAMES D. FRARY, of NewBritain, county of Hartford and State of Connecticut, have inventedcertain new and useful ImprovementsV in the Manufacture of Knives 5 andto enable others skilled in the art to make and use the same I willproceed to describe its peculiarity by referring to the drawings, inwhich the same letters indicate like parts in each of the figures.

The nature of this improvement will be understood from the specificationand drawings. The object desired to be attained thereby is to unite orsecure the bolster in one piece of met-al in its proper place upon theshank of the blade, and to secure the handle (made in two parts) to theshank by (meta-l bars) the same means by which the bolster is secured.

In the accompanying drawings, Figure l shows a knife in a finishedstate. Fig. 2 shows an edge sectional view of the blade withthc bolsterlsecured thereto. Fig. 3 shows an edge sectional view of a blade, havinga two-part handle secured thereto.

a is the blade. a is the shank. a" is the bolster. c is the materialwhich forms the handle proper. d are connections or gripingbars. rIheblade a, with its shank, is rst made in the usual way. The holes throughwhich the molten mtal passes are made somewhat larger than what are madewhere the bolster and handle are secured by rivets.

Then the shank is tinned by the common way of tinning, for the purpose,iirst, so that the molten metal will adhere thereto in the act orprocess of forming the bolster thereon, whereby the bolster itself andthe bolster and blade become one tirmlyunited piece of metal; or, inother words, the bolster is formed on the blade in one piece of metal,and not only so, but so that it may properly be said that the bolsterand the blade or shank are one piece of metal; and, second, to preventrust from forming on the surface and edge between the surface of thehandle and the shank, which is commonly seen in knife and fork handlesnew innse, giving a very dingy unwholesome appearance thereto. Thistinning is not necessary to the carryin gout of the main principle ofthis invention, but it is believed will essen* tially improve thearticle both in appearance and utility. y

To effect this improvement, (forming the proper molds are prepared,(which may be done in several different ways familiar to a practicalperson,) so that the blade or the shank of the blade, with or withoutthe parts of the handle, may be placed therein, and the molten metalpoured therein. Thus it will be clearly seen that by placing the bladeor the shank of the blade, tinned or untinned, into a properly-formedmold, either with or without the parts which make up the handle, thebolster will be perfectly formed in one piece of metal onto the blade;and, further, that when the handles with the shank of the blade aremeans, of pouring molten metal bars d into places prepared therefor,which, in cooling, firmly gripe the handles together on the shank. Inthis way I am enabled toV make a knife having a solid bolster formed oneach side and kconnecting together through anopening in 'the blade orshank in one piece of metal, and having a handle secured thereon withoutriv' etin g, thus producing a neat, tasteful, and desirable article ofmanufacture.

y I believe I have thus shown the nature and mode of proceeding toeffect this improvement. i

What I claim, therefore, and desire to secure by Letters Patent, is-

1. Forming a bolster, a, upon a blade, a, having perforations in thecenter thereof, through which the metal is poured to form a solidbolster, substantially as described.

2. Securing the handles c, made in two parts, having holes therein tocorrespond with those formed in the blade, and countersunk, so that themetal ,poured therein will rmly gripe the parts together, substantiallyas described.
